Hi, I am very much inexperienced with electrics so don't worry I will not be completing this job myself - I am just looking for some information while planning a project. Layman's terms where you can please. I am planning on knocking down and rebuilding my garage. There is currently power supplied to the garage however, it doesn't seem clear how. There is no 'garage' circuit in the consumer unit. Given the state of other electrics dealt with in this house - the living room ring main bypassing the fuse box entirely for example - it wouldn't surprise us that it's simply an extension of an existing ring main of sockets. The new building will be a wood workshop and will therefore need power. There will be a low power lighting circuit and I need enough juice to use power tool and a shop vacuum at the same time. I'm trying to price everything up before we make a start and have come stumped around the electrical connections area. It's my understanding - correct me if I'm wrong - that a cable needs to be run from the existing consumer unit in the house, out to the workshop. This needs to be buried in armoured conduit etc. But my main concern is with the consumer unit. There is only 1 blank left, and it seems to be labelled as not being covered by an RCD (it is to the right of the RCDs). My question, finally, is would an electrician add an MCB to this blank, and run a wire outside (following code re burying/warning tape etc, simple as that? or are there other issues I am missing i.e. for each circuit in the workshop there needs to be a separate cable from the house? or we need a larger consumer unit for the additional circuits as it needs to also be covered by an RCD? etc etc? Any and all help is very much appreciated!
